BARRE L on EG MADE OF PULP;

To all whorn it may concern: 7 Be it known that I, FRANK EUGENE KEYEs,

. of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Barrels or Kegs Made of Pulp; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it'appertains to make and use the same. I

, My invention relates to an improvement in barrels or kegs made of pulp, the object being to. construct a barrel or keg that will not be affected by heat or cold or by dampness and one that will be practically water-tight and, ifdesired, fireproof, thus specially adapting it for holding plosives.

WVith these ends in view my invention con-- sists in a barrel or keg made of pulp, the body being without seam'or joint and the ends or heads each being of a single integral sheet of the same material and provided with a pcripheral rib or projection adapted to be forced or sprung into a croze in the barrel or keg body. v

My invention further consists in the details of construction, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings,'Figure 1 is a viewin section of a barrel or keg embodying my invention. means for locking the heads to the body and for protecting the free ends of the body.

1 represents the body of a barrel or keg made of pulp. This body is formed. on the winding-roll of a pulp-machine and is removed therefrom by collapsing the windingroll or otherwise, thus leaving the body in true cylindrical or tapering form, as desired.-

Formed in the inner surface of the body 1 are the grooves or crozes 2 to receive projecting edges or shoulders 3, formed on the heads or ends 4. These grooves may be formed after the body 1 has been'dried by a cutting-tool; but I prefer to form them while the pulp composing the body is in. its moist condition and preferably immediately after 7 removing the body from the winding-roll of the pulp-machine.

The heads and ends t are cut from a moist sheet of pulp-and subsequentlyshaped between dies and dried. In Figs. 1 and 2 the heads or ends A are made concavo-convex, with a peripheral flange 5 extending out from the edge of the concave face. a The concave Specification of Letters Patent. 7 Application filed February 10, 1904- Serial No. 192,951.

surfaces ofthe heads face outwardly when in position in the barrel or keg body, with the free edgeiof the flange 5 flush with the end of the barrel. 7 The peripheral projection or rib 6O 3 on'the head is located, preferably, on a line with the concave face of the head and, as before stated, rests in a croze 2, formed in the body of the barrel or keg.

I prefer to construct the heads or-ends of a 5' conc'avo-convex shape with the concave surfaces outwardly, for the reason that the internal pressure thereagainst tends to bind them more securely in position.

In the construction shown :in Fig. 2 a metalv hoop or band 6 embraces the ends of the body 1 and is turned over, so as to overlap the 'ends of the heads or ends,lthus not only protecting these ends from undue wear, but also assisting materially in'preventing any expansion of the body after the heads and ends have been secured in place..

' In 1 instances the heads arevprovided with filling-holes 7 which may be plain or screwthreaded and closed by a plug or stopper of any approved design.

In order to secure the heads or ends in place, the ends of the body are expanded or pressed outwardly, so'as topermit the heads or ends to be started, after, which pressure i applied to the centers of the heads or ends and the latter forced inwardly until they seat themselves in the crozesfi If desired, a cement may be applied at the juncture of the heads or ends to more securely lock them in place.

Barrels or kegs made whollyof fiber or pulp may beimpregnated with water and fire proofing substances during the operation of felting the fiber, thus rendering the article made from the pulp specially applicable for storing and transporting explosives. I

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown'and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction shown and described; but,

Having. fully described my invention, what 1. A seamless barrel or keg provided near each end with an internal groove, of heads to enter the respective ends of the barrel or.keg

mally that they can be sprung into the body "I claim as new, and desire to secure by Letters 95 Patent, is

IIO

and the peripheral ribs sprung into theinternal grooves in the body, whereby the periph eral flanges of the heads will be normally pressed against the wall of the body and the ribs maintained in the internal grooves.

2. As a new article of manufacture, a barrel or keg comprising a seamless pulp-body having an internal groove near the end, aconcavo-convex head or end alsornade of a single sheet of pulp and provided with a peripheral rib to enter said internal groove and a metal hoop encircling the end of the body of the barrel or keg and overlapping the periphery of the head or end. In testimony whereof I havesigned this 5 specification in the presence of two subscribing witnesses.
